Soot types
| Soot | How it behaves | How it is removed |
|---|---|---|
| Dry soot | Powdery, lifts easily | HEPA vacuum then dry sponge |
| Wet or smeary soot | Greasy, smears if wiped | Degreaser after dry removal |
| Protein residue | Hard to see, strong smell | Enzyme or specialty cleaners |
| Fuel oil soot | Fine, spreads widely after furnace puff-back | HEPA vacuuming and detailed cleaning |
Why wiping makes it worse
Soot particles are tiny and oily. Wet rags push them into the pores of paint and drywall, turning a surface stain into a permanent one. Dry methods lift particles before they are wet.
Steps
- HEPA vacuum from top to bottom.
- Chemical dry sponge on walls and ceilings.
- Wet clean with a degreaser if residue remains.
- Seal stains with a primer.
- Clean HVAC and replace filters.
Soot is acidic and damages metals, glass and finishes within days. Fast action matters. See fire damage cleanup for the full cleanup and smoke stain removal for stains that remain.
